Saw the same ad in the past few days on a Hobbyist Haven ad.  As CPDDET said, looks pretty cool, may be useful and, unfortunately, I'm a sucker for little things like this. 🤷‍♂️😅

Hard to resist, isn't it? I'm a tool addict.

 This is cool tool. I would be especially interested in axial center drilling. Thinking over it I can see that to have a good centered hole I must use very accurately dimensioned round dowel stock. I measured my so called 4 mm dowels and they are all 3.87 mm. I have to put it into a groove marked as 4 mm DIA. The drilled hole will not be at axial center. I am afraid it will be very noticeable by the eye.

But still very hard to resist the temptation.

Here it is for a third of a price.

Would have to use a dowel plate first to assure the correct diameter.

I had not much success using a dowel plate on wood. I found no way to draw it through holes. It beaks if drawn or pushed through. May be I need to know some technics? How to draw the wood through the holes?

I'm sure there are examples on youtube.

Interesting tool, now that I have a mill this is some I would like to try to recreate.

Oh, by the way, did someone said, "we are suckers for tools"?🙂

Keep the rest of us mill owners posted on your efforts.

I am sure you'd enjoy making it but your expenses will be 10 times the purchase price of $25 US.

The problem is, that it only works for the set of diameters provide in the tool ...

True. It may work best for builds at a certain scale. Larger dowel drilling can be done in various other ways. But for some it may be a big time saver.

I tried my old jewelers draw plate today. I easily drew my 3.87 mm wood dowel into 3.5 mm and 1.78 bamboo toothpick into 1.5 mm. These are the sizes required for the tool in question.

I would find it more useful if it went down to 0.5 mm (0.020") and 0.25 mm (0.010").
